(1)Represents the remaining weighted average contractual life in years.
(2)Aggregate intrinsic value represents the total pre-tax intrinsic value (i.e., the difference between the Company’s stock price on the last trading day of the quarter and the option exercise price, multiplied by the number of shares) that would have been received by the option holders if they had exercised their options on the last day of the quarter. Options with exercise prices above the stock price on the last trading day of the quarter are excluded from the calculation of intrinsic value. The intrinsic value will change based on the fair market value of the Company’s stock.
